This example uses a COBOL program with embedded SQL to DROP an index and DROP a table. In the world of programming there are many ways to solve a problem. This suite of programs is provided as a COBOL programming example of one of the possible solutions.
CAUTION: the following example describes how to DROP a table and this will delete all the data stored in the table.
The following is the Windows Command file (CUQDT1E1.CMD) that is required to run as a job on a PC using Micro Focus Studio/EE.

rem * This set of programs illustrate the use of embedded SQL in a COBOL
rem * program that Deletes (or Drops) a Table of information for the
rem * Customer Master Data Base.

rem * This technique provides for the use of a single COBOL source
rem * program that will run on ZOS, Windows or UNIX.
rem *
rem * This set of programs will run on a Personal Computer with Windows
rem * and Micro Focus Net Express or Mainframe Express.
